While still aluminum, Yamaha has changed the methods of
casting the aluminum pieces. The spars are now extruded.
The electric starter button is positioned on the right handlebar,
next to the throttle. No more kicking for YZ450F owners.
The engine is visually much more upright than in the past. The
angle has been rotated 2 degrees forward.
The YZ450F comes with a Wi-Fi feature that allows owners to
call it up on their smartphone and say, “Hey, what’s up?”
